• 1 x Ever-So-Handy Power Cord
• This Lovely User Manual
Getting It Out Of The Box
Congratulations! Your audiences will be blown away when they take a gander at the
colored fog eects of your new AtmosFEAR® 221b! Now that you’re the proud owner
of a AtmosFEAR® 221b (or hopefully, 221b’s), you should carefully unpack the box
and check the contents to ensure that all parts are present and in good condition. If
anything looks as if it has been damaged in transit, notify the shipper immediately
and keep the packing material for inspection. Again, please save the carton and all
packing materials. If a xture must be returned to the factory, it is important that
the xture be returned in the original factory box and packing.
Powering Up!
All xtures must be powered directly o a switched circuit and cannot be run o
a rheostat (variable resistor) or dimmer circuit, even if the rheostat or
dimmer channel is used solely for a 0% to 100% switch.
AC Voltage Switch - Not all xtures have a voltage select switch, so please verify that
the xture you receive is suitable for your local power supply. See the label on the
xture or refer to the xture’s specications chart for more information. A xture’s
listed current rating is its average current draw under normal conditions. Check the
xture or device carefully to make sure that if a voltage selection switch exists that it
is set to the correct line voltage you will use.
Warning! Verify that the voltage select switch on your unit matches the
line voltage applied. Damage to your xture may result if the line voltage
applied does not match the voltage indicated on the voltage selector switch.
All xtures must be connected to circuits with a suitable Ground (Earthing).

Fuse Replacement
AtmosFEAR® 221b is equipped with an easy-to-use, push-button thermal cir-
cuit breaker. The button will extend for visual trip indication, and can simply be
pushed back in to be reset.
Connecting A Bunch of AtmosFEAR® 221b Units
You can use a serial data link to run shows using a DMX-512 controller or to
run shows on two or more units set to sync in master/slave operating mode.
The combined number of channels required by all the units on a serial data link
determines the number of units the data link can support.
Units on a serial data link must be daisy chained in one single line. Also, con-
necting more than 32 units on one serial data link without the use of a DMX
optically-isolated splitter may result in deterioration of the digital DMX signal.
The maximum recommended cable-run distance is 500 meters (1640 ft). The
maximum recommended number of units on a serial data link is 32 xtures.
Data/DMX Cabling
You should use data-grade cables that can carry a high quality signal and are
less prone to electromagnetic interference. For instance, Belden© 9841 meets
the specications for EIA RS-485 applications. Standard microphone cables will
“probably” be OK, but note that they cannot transmit DMX data as reliably over
long distances.
3-Pin??? 5-Pin??? Huh?!?
This unit is ideal for use with any DMX controller. It comes equipped with both
3-pin and 5-pin XLR in/out sockets with standard pin conguration:
Conductor 3-Pin Female (Output) 5-Pin Male (Input)
Ground/Shield Pin 1 Pin 1
Data 1- (Primary Data Link) Pin 2 Pin 2
Data 1+ (Primary Data Link) Pin 3 Pin 3
Data 2- (Optional Secondary Data Link) Pin 4 Pin 4
Data 2+ (Optional Secondary Data Link) Pin 5 Pin 5
This fog machine comes equipped with a 20A, push-to-
reset thermal circuit breaker.
3. SETUP

Page 7
AtmosFEAR® 221b Manual - Rev. B (c) 2019 Blizzard Lighting, LLC
CAUTION: Do not allow contact between the common and the xture’s chassis
ground. Grounding the common can cause a ground loop, and your xture may
perform erratically. Test cables with an ohm meter to verify correct polarity and
to make sure the pins are not grounded or shorted to the shield or each other.
Take It To The Next Level: Setting Up DMX Control
Step 1: Connect the male connector of the DMX cable to the female connector
(output) on the controller.
Step 2: Connect the female connector of
the DMX cable to the rst xture’s male
connector (input). Note: It doesn’t
matter which xture address is the
rst one connected. We recommend
connecting the xtures in terms of their
proximity to the controller, rather than
connecting the lowest xture number
rst, and so on.
Step 3: Connect other xtures in the
chain from output to input as above.
Place a DMX terminator on the output
of the nal xture to ensure best
communication.
Fixture Linking (Master/Slave Mode)
1. Connect the male 3/5-pin connector side of the DMX cable to the output
(female) 3/5-pin connector of the rst xture.
2. Connect the end of the cable coming from the rst xture which will have a
(female) 3/5-pin connector to the input connector of the next xture consist-
ing of a (male) 3/5-pin connector. Then, proceed to connect from the output as
stated above to the input of the following xture and so on.
Mounting & Rigging
• This unit may be used on the oor, or mounted in any SAFE position provided
there is enough room for ventilation.
• Mount the xture using a suitable “C” or “O” type clamp. The clamp should
be rated to hold at least 10x the unit’s weight to ensure structural stability. Do
not mount to surfaces with unknown strength, and ensure properly “rated” rig-
ging is used when mounting xtures overhead.
• Adjust the angle by loosening both knobs and tilting the unit. After nding
the desired position, retighten both knobs.
• Safety cables MUST ALWAYS be used.
• Never mount in places where the unit will be exposed to rain, high humidity,
extreme temperature changes or restricted ventilation.

5. APPENDIX
A Quick Lesson On DMX
DMX (aka DMX-512) was created in 1986 by the United States Institute for Theatre
Technology (USITT) as a standardized method for connecting lighting consoles to lighting
dimmer modules. It was revised in 1990 and again in 2000 to allow more exibility. The
Entertainment Services and Technology Association (ESTA) has since assumed control over
the DMX512 standard. It has also been approved and recognized for ANSI standard clas-
sication.
DMX covers (and is an abbreviation for) Digital MultipleXed signals. It is the most common
communications standard used by lighting and related stage equipment.
DMX provides up to 512 control “channels” per data link. Each of these channels was origi-
nally intended to control lamp dimmer levels. You can think of it as 512 faders on a lighting
console, connected to 512 light bulbs. Each slider’s position is sent over the data link as an
8-bit number having a value between 0 and 255. The value 0 corresponds to the light bulb
being completely o while 255 corresponds to the light bulb being fully on.
DMX data is transmitted at 250,000 bits per second using the RS-485 transmission stan-
dard over two wires. As with microphone cables, a grounded cable shield is used to prevent
interference with other signals.
There are ve pins on a DMX connector: a wire for ground (cable shield), two wires for
“Primary” communication which goes from a DMX source to a DMX receiver, and two wires
for a “Secondary” communication which goes from a DMX receiver back to a DMX source.
Generally, the “Secondary” channel is not used so data ows only from sources to receiv-
ers. Hence, most of us are most familiar with DMX-512 as being employer over typical
3-pin “mic cables,” although this does not conform to the dened standard.
DMX is connected using a daisy-chain conguration where the source connects to the input
of the rst device, the output of the rst device connects to the input of the next device,
and so on. The standard allows for up to 32 devices on a single DMX link.
Each receiving device typically has a means for setting the “starting channel number” that
it will respond to. For example, if two 6-channel xtures are used, the rst xture might
be set to start at channel 1 so it would respond to DMX channels 1 through 6, and the next
xture would be set to start at channel 7 so it would respond to channels 7 through 12.
The greatest strength of the DMX communications protocol is that it is very simple and
robust. It involves transmitting a reset condition (indicating the start of a new “packet”),
a start code, and up to 512 bytes of data. Data packets are transmitted continuously. As
soon as one packet is nished, another can begin with no delay if desired (usually another
follows within 1 ms). If nothing is changing (i.e. no lamp levels change) the same data will
be sent out over and over again. This is a great feature of DMX -- if for some reason the
data is not interpreted the rst time around, it will be re-sent shortly.
Not all 512 channels need to be output per packet, and in fact, it is very uncommon to nd
all 512 used. The fewer channels are used, the higher the “refresh” rate. It is possible to
get DMX refreshes at around 1000 times per second if only 24 channels are being trans-
mitted. If all 512 channels are being transmitted, the refresh rate is around 44 times per
second.
In summary, since its design and evolution in the 1980’s DMX has become the standard
for lighting control. It is exible, robust, and scalable, and its ability to control everything
from dimmer packs to moving lights to foggers to lasers makes it an indispensable tool for
any lighting designer or lighting performer.

Keeping Your AtmosFEAR® 221b As Good As New
The fogger you have received is a rugged, tough piece of professional
equipment, and as long as you take care of it, it will take care of you. That said,
like anything, you’ll need to take care of it if you want it to operate as designed.
You should absolutely keep the xture clean, especially if you are using it in an
environment with a lot of dust, fog, haze, wild animals, wild teenagers or spilled
drinks.
Cleaning Instructions:
1.) You should follow these instructions after approximately 40 hours of use.
2.) Take o the nozzle before heating the fog machine, and clean the nozzle
with straight vinegar.
3.) To clean the tank, pour in and run a solution of 80% distilled water and 20%
white vinegar through the machine. When empty turn o the machine.
4.) Wait for it to cool down, re-install the nozzle, and you can now add more
uid to prepare for its next use.
Returns (Gasp!)
We’ve taken a lot of precautions to make sure you never even have to worry
about sending a defective unit back, or sending a unit in for service. But,
like any complex piece of equipment designed and built by humans, once in a
while, something doesn’t go as planned. If you nd yourself with a xture that
isn’t behaving like a good little xture should, you’ll need to obtain a Return
Authorization (RA).
Don’t worry, this is easy. Just go to our website and open a support ticket at
www.blizzardpro.com/support, and we’ll issue you an RA. Then, you’ll need to
send the unit to us using a trackable, pre-paid freight method. We suggest
